+    The sbseparator class is defined to separate SIGNAL and IMAGE

+    It also helps supressing emmission of IMAGE sideband.
+    *** WARNING *** THIS MODULE IS EXPERIMENTAL
+    Known issues:
+    - Frequencies of IMAGE sideband cannot be reconstructed from
+      information in scantable in sideband sparation. Frequency
+      setting of SIGNAL sideband is stored in output table for now.
+    - Flag information (stored in FLAGTRA) is ignored.
